The Minto mine commenced Yukon mining operations in 2007 as an open pit mine. In 2012 the company began underground development on the Minto South Deposits while continuing to mine additional open pits as the primary mining method. Today, the mining is entirely underground and we are currently producing in the Copper Keel ore body.

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or 2 kilometers.

Surface mining, which includes strip mining, openpit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the predevelopment steps are complete. Underground mining uses shafts and tunnels to access deeplyburied mineral deposits, while the overlying rock is left in place.
